	M747 Abdullah Sulaiman Al-Ayed, Lassaad Baklouti and Abdelwaheb Hamdi Short Note: 5,11,17,23-Tetra-tert-butyl-25-(2’-pyridylmethylamidocarbonylmethyl)-calix[4]arene Molbank 2012, 2012(1), M747; doi:10.3390/M747 Received: 13 December 2011 / Accepted: 4 January 2012 / Published: 10 January 2012 Show/Hide Abstract | Download PDF Full-text (263 KB) |  Abstract: 5,11,17,23-tetra-tert-butyl-25-(2’-pyridyl methyl amidocarbonylmethyl)-calix[4]arene (3) has been synthesized in the cône conformation through reaction of the corresponding mono-ester with 2-aminomethylpyridine (picolylamine) and characterised using 1H NMR and MALDI-TOF mass spectral data as well as elemental analyses.
	M748 Obaid Afzal, Sandhya Bawa, Suresh Kumar and Rajiv K. Tonk Short Note: Nꞌ-{[2-(Piperidin-1-yl)quinolin-3-yl]methylene}pyridine-4-carbohydrazide Molbank 2012, 2012(1), M748; doi:10.3390/M748 Received: 6 January 2012 / Accepted: 10 January 2012 / Published: 18 January 2012 Show/Hide Abstract | Download PDF Full-text (175 KB) |  Abstract: Nꞌ-{[2-(piperidin-1-yl)quinolin-3-yl]methylene}pyridine-4-carbohydrazide 2 has been synthesized through condensation of 2-(piperidin-1-yl)quinoline-3-carbaldehyde 1 with isonicotinic acid hydrazide (INH) in absolute ethanol. The structure of the title compound 2 was established on the basis of IR, 1H-NMR, 13C-NMR and mass spectral data.
	M749 Thoraya A. Farghaly and Sobhi M. Gomha Short Note: Ethyl 3-{2-[(3-Methyl-1H-indol-2-yl)carbonyl]­hydrazinylidene}­butanoate Molbank 2012, 2012(1), M749; doi:10.3390/M749 Received: 6 January 2012 / Accepted: 4 February 2012 / Published: 7 February 2012 Show/Hide Abstract | Download PDF Full-text (209 KB) |  Abstract: The title compound, ethyl 3-{2-[(3-methyl-1H-indol-2-yl)carbonyl]hydrazinylidene} butanoate (3), was prepared via reaction of 3-methyl-1H-indole-2-carbohydrazide (1) and ethyl 3-oxo­butanoate (2) under reflux. The structure of the synthesized compound was assigned on the basis of elemental analysis, IR, 1H-NMR, mass spectral and X-ray data.
	M750 Gadada Naganagowda and Amorn Petsom Short Note: 4-[(2-Hydroxy-4-pentadecylbenzylidene)amino]-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one Molbank 2012, 2012(1), M750; doi:10.3390/M750 Received: 7 February 2012 / Accepted: 28 February 2012 / Published: 29 February 2012 Show/Hide Abstract | Download PDF Full-text (84 KB) |  Abstract: Novel 4-[(2-hydroxy-4-pentadecylbenzylidene)amino]-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one was prepared via condensation of 2-hydroxy-4-pentadecylbenzaldehyde (1) with 4-amino-1,2-dihydro-2,3-dimethyl-1-phenylpyrazol-5-one (2) in ethanol/acetic acid under reflux. The structure of the synthesized compound was assigned on the basis of elemental analysis and spectral data.
	M751 Shylaprasad Durgadas, Khagga Mukkanti and Sarbani Pal Short Note: N-(2-Phenoxy-4-(3-phenoxyprop-1-ynyl)phenyl)methane Sulfonamide Molbank 2012, 2012(1), M751; doi:10.3390/M751 Received: 7 February 2012 / Accepted: 29 February 2012 / Published: 2 March 2012 Show/Hide Abstract | Download PDF Full-text (213 KB) |  Abstract: The title compound, N-(2-phenoxy-4-(3-phenoxyprop-1-ynyl)phenyl) methanesulfonamide was synthesized in high yield by Sonogashira cross coupling of N-(4-iodo-2-phenoxyphenyl)methanesulfonamide with 3-phenoxyprop-1-yne. The structure of the compound was fully characterized by IR, 1H and 13C NMR, Mass spectra and elemental analysis.
